Abstract
An antenna structure is disposed on a metal unit and includes a first slot, a second slot, a grounding portion and a short-circuiting portion. The first slot is formed on the metal unit along an axis direction and configured to receive a signal feed. The second slot is formed on the metal unit along the axis direction and separated from the first slot by a distance along the axis direction. The grounding portion is coupled to the metal unit. The short-circuiting portion crosses the second slot and is coupled to the grounding portion.
